Which factor is NOT included in a TAF report?

The correct answer is that current temperature readings are not included in a TAF report. Terminal Aerodrome Forecasts are specifically designed to provide forecasted weather conditions at an airport for a set period, typically covering a 24- or 30-hour window. The TAF focuses on aspects such as projected wind conditions, expected visibility, and forecasts for precipitation, all of which are essential for flight planning and operations. These elements help pilots and air traffic controllers anticipate weather impacts on safety and aircraft performance.

In contrast, current temperature readings are part of METAR reports, which provide actual, observed weather conditions rather than forecasts. This distinction is crucial for understanding the difference between TAF and METAR reports, and highlights the specific purpose of TAFs in providing future weather conditions rather than current ones.
